Specification of Letters Patent.

Application filed October 7, 1910. Serial No. 585,896.

To all whom it 'may concern:

Be it known that I, HEINRICH SssMANN, engineer, a subject of the Emperor of Germany, residing at 8-12 Rotherstrasse, Berlin, in the German Empire, have invented certain new and useful Improvements in Incandescent Gas- Burners, of which the following is a specification.

Incandescent gas burners are already l0 known in which the upper part of the burner carrying the gallery for the cylinder is fitted with a narrower burner head than that of a standard incandescent gas burner. In these known arrangements the upper part of the burner carrying the gallery, what is known as the crown of the burner, is, in well known manner slipped over the Bunsen tube, so that the heat coming from the flame, is, by conduction and radiation transmitted to the burner head and thence to the outer tubular part of the burner, the crown of the burner.

The object of the present invention is an arrangement for transforming the usual incandescent gas burner of standard size into what is known as a Bijou or Gem burner, that is to say a smaller burner. This transformation is effected as follows: Into the burner crown of a standard incandescent gas light a tube is slipped, after removal of the head ring and the parts in the burner head, which tube at the top is closed /by a gauze plate and so far projects beyond t-he crown tube of the burner as t0 permit another mantle to be placed on.

With the new arrangement the additional advantage is obtained that the heat passing from the flame to the burner head by conduction and radiation is conducted into the interior of the burner. By this means the mixture of air and gas before entering the ame is better heated and the temperature of the flame, consequently the lighting effect of the burner, will be increased.

One form of construction of the new arrangement is shown in the accompanying drawings.

Figure 1 represent-s the burner crown of an ordinary incandescent gas burner to which are applied the parts shown in Figs.

2 and 8. Figs. 2 and 3 show ordinary ttings of this 'class of burner. Fig. 4 shows a part to be slipped into the Bunsen tube of a burner to be converted. Figs. 5 and 6 show a complete burner fitted up according to this invention, in section and in plan re- -spectivelv the parts shown in Figs. 2 and 3 are removed, and instead of these the t-ubular piece shown in Fig. 4 is placed into the burner tube a of Fig. l. The fitting Fig. 4 in its lower part is of such width that it may be slipped into the Bunsen tube as shown in Fig. 5 and just fit it nicely. The fitting tube can be retained byvany suitable means, for instance, by the cap e. l

In Fig. 5 the complete arrangement is shown; it will be seen that the fitting tube is within the Bunsen tube so that the mixture of air and gas comes into contact therewith and the heat conducted from the burner head is advantageously transmitted to the mixture of air and gas.

In its details the construction shown in the drawings may be varied in different ways without in any way adecting the essence of the invention. Instead of the top plate having triangular slots as shown in the drawings the fitting Figs. 4 and 5 may have a differently arranged top plate. Instead of being held by the cap e the tube tting may be xed by other means.

Claims.
